How Many Dependents Should I Claim On My W4?

Taxpayers who are financially responsible for other people can receive tax breaks by claiming them as dependents, but this does not necessarily mean they should claim all of their dependents on their W-4 tax forms.


Key Takeaways:

  • An IRS W-4 Form, Employee’s Withholding Certificate, is a tax form used by employees to tell an employer how much tax they would like to be withheld from their paychecks.
  • The more dependents a taxpayer claims on their W-4 form, the less tax will be withheld from their paychecks, and the higher their paychecks will be. Claiming fewer allowances on their W-4 form will result in more tax being withheld from their paychecks and a lowered income with each payment.
  • Qualifying dependents that can be claimed on a W-4 form include qualifying children and qualifying relatives who meet the relationship, residency, age, and income requirements set forth by the IRS, and they cannot be claimed as a dependent by another taxpayer.
  • Taxpayers who claim dependents on their W-4 forms may be eligible for the adoption tax credit, the American opportunity tax credit, the child and dependent care credit, the child tax credit and additional child tax credit, the credit for other dependents, the earned income tax credit, the lifetime learning credit, and the medical expenses deduction.

How Many Dependents Should I Claim On W4?

Taxpayers can decide how many dependents they wish to claim on their W-4 forms, which impacts how much tax their employer withholds from their paycheck. While it is required for taxpayers to claim all of their dependents on their tax returns so the IRS can issue tax breaks, taxpayers can choose how many dependents they can claim on their W-4 to influence how much they are paid in each paycheck, and ultimately if they will owe money or be eligible for a tax refund when they file their tax return. 

When individuals are working on their financial planning, they can decide if they need to receive as much of their earnings as possible in each of their paychecks at the risk of owing a tax liability when they file their taxes, or if they would prefer to potentially have too much tax withheld now to later receive a tax refund.

What Is IRS Form W-4?

IRS Form W-4, Employee’s Withholding Certificate, is a type of tax form that is used to tell an employer how much tax to withhold from their employee’s paychecks based on their filing status, job adjustments, credits, and deductions.

What Are IRS Allowances On IRS Form W-4?

IRS withholding allowances impact the amount of money employees are paid in each paycheck by determining how much of their earnings are withheld for taxes and paid to the IRS. These tax exemptions reduce the amount of income tax that employers withhold from their employee’s paychecks based on the information the employees list in their W-4 forms.

During the tax season when taxpayers calculate their annual tax liability and evaluate how much they have already paid through tax withholding, they will find that they either owe additional tax payments to the IRS, have paid exactly the amount of tax that was due, or that they overpaid their tax liability and will be issued a tax refund.

How Do Tax Allowances Impact A Tax Bill?

Tax allowances impact how much a person owes when they file their income tax returns based on how many allowances the taxpayer claimed on their W-4 tax form. 

The more allowances a taxpayer claims, the less tax will be withheld from their paychecks. People may choose to claim more allowances to help them afford their regular living expenses as this will cause them to receive bigger paychecks whenever they get paid. However, claiming many dependents on their W-4 form could result in a higher tax bill during the tax season if they underpaid their tax liability, which could cause significant financial stress if the tax owed is a large sum. For this reason, it is important to consider what a reasonable tax withholding amount would be.

If taxpayers claim fewer allowances, then more money will be withheld from their paychecks for taxes. This will result in employees receiving less money in their paychecks, but it will lower their tax liability during the tax season. Additionally, if the taxpayer requested that their employer withhold too much tax that resulted in them overpaying what they owed the IRS for taxes, they would be eligible to receive a tax refund.

How To Calculate Tax Withholding Using The IRS Tax Estimator

The IRS offers a tax calculator to help taxpayers estimate how much tax they should have withheld from their paychecks to reduce how much they owe during the tax season. The tax withholding estimator can be used if taxpayers have their paystubs, other income information, and their most recent tax return available.

Who Can Claim Dependents On Their Tax Returns?

Taxpayers can claim dependents on their tax returns in the following situations:

  • The taxpayer, and their spouse if they are filing jointly, cannot be claimed as a dependent by another taxpayer.
  • Taxpayers are allowed to claim a married person who files a joint return as a dependent only if that joint return is solely intended to claim a refund of income tax withheld or estimated tax paid.
  • The dependent being claimed is a U.S. citizen, U.S. national, U.S. resident alien, or a resident of Canada or Mexico.
  • The dependent being claimed is a qualifying child or a qualifying relative.

What Is A Qualifying Dependent?

Dependents are individuals other than the taxpayer or their spouse who are qualified to be claimed on someone else’s tax return. A qualifying dependent may be a child or relative that meets the IRS requirements to be claimed on their tax return. For a taxpayer to claim dependents on their W4 form, each dependent must meet requirements based on whether they are a qualifying child or a qualifying relative.

Requirements For All Qualifying Dependents:

  • A qualifying dependent must be a U.S. citizen, U.S. national, U.S. resident alien, or resident of Canada or Mexico.
  • The dependent is only being claimed by one taxpayer on their tax returns.
  • The dependent cannot claim another dependent on their own tax return.
  • The dependent cannot be claimed if they are married and filing jointly with their spouse.

Requirements For Qualifying Children:

  • A qualifying child can be related to the taxpayer as their daughter, son, stepdaughter, stepchild, eligible foster child, sister, brother, stepsister, stepbrother, half-sister, half-brother, adopted child, or an offspring of any of these family members.
  • A qualifying child must meet the age requirement of being under the age of 18. If they are a full-time student, dependents must be under the age of 24. If the qualifying child is permanently disabled, there is no age limit for them to be claimed as a dependent.
  • A qualifying child must live with the taxpayer for more than six months of the year. There are certain exceptions to this rule.
  • A qualifying child must be financially supported by the taxpayer. If the child has a job, they must not provide more than half of the income to support themselves.

Requirements For Qualifying Relatives:

  • Qualifying relatives must live with the taxpayer at their residence for the full duration of the year. Otherwise, they must qualify as one of the “relatives who do not live with you” in Publication 501.
  • Qualifying taxpayers must have had a gross income of no more than $4,400 in 2022.
  • Qualifying taxpayers must be at least 50% financially supported by the taxpayer every year.

Which Credits And Deductions Are Available When Claiming Dependents On A W4 Tax Form?

Adoption Tax Credit

The adoption tax credit is a non-refundable tax credit that allows taxpayers to claim the expenses that they have paid when adopting a child. For 2023, the maximum credit amount is $15,950 per adopted child, and for 2022, the maximum credit amount was $14,890 per adopted child.

Although excess funds from this credit cannot be claimed as a tax refund, any remaining credit value can be carried over for up to five years.

American Opportunity Tax Credit

The American opportunity tax credit (AOTC) offers a maximum annual credit of $2,500 per eligible student for their first four years of higher education. This is a partially refundable tax credit, so up to 40% of any remaining credit amount can be refunded to the taxpayer, with a maximum refund of $1,000 from this credit. 

Child And Dependent Care Credit

The child and dependent care credit is a refundable tax credit that can be applied towards daycare expenses for qualifying dependents while the taxpayer is at work or school. If claiming one dependent, the value of this credit amounts to 20% to 35% of up to $3,000, and if claiming two or more dependents, this credit is worth 20% to 35% of up to $6,000. 

Child Tax Credit And Additional Child Tax Credit

For the 2022 tax year, the child tax credit is valued at up to $2,000 for qualifying dependents under the age of 17 if the single-filing taxpayer has a gross income of less than $200,000 per year or married filers have a gross income of less than $400,000.

Credit For Other Dependents

The IRS offers a non-refundable credit for other dependents with a value of up to $500 for each qualifying relative they claim on their tax return.

Earned Income Tax Credit

The earned income tax credit (EITC) is a refundable tax credit offered to eligible low- to moderate-income workers, especially those who claim dependents on their tax return. Depending on their filing status and the number of dependents they are financially responsible for, for the 2023 tax year, this credit is worth between $600 and $7,430.

Lifetime Learning Credit

The lifetime learning credit (LLC) is a tax credit for eligible students to help pay for tuition and tuition-related expenses for their higher education. This credit is worth up to $2,000.

Medical Expenses Deduction

Taxpayers who pay for medical expenses for their qualifying child or qualifying relative who is claimed as a dependent may qualify for the medical expenses deduction. This tax deduction allows eligible taxpayers to deduct medical care expenses that were more than 7.5% of their adjusted gross income and must be claimed as an itemized deduction.

Is The Number Of Dependents A Taxpayer Has The Same As The Number Of Allowances They Can Claim?

While the number of dependents a taxpayer is financially responsible for and the number of allowances they can claim on their W-4 tax form is related, this number may not necessarily lead to the appropriate withholding amount for a taxpayer’s specific tax situation.

There may be other allowances aside from dependents that taxpayers can claim on their W-4 form.

When Should Taxpayers Update Their Withholding Allowances?

Taxpayers can technically update their withholding allowances whenever they want by filing a new W-4 tax form with their employer, but it is generally recommended to wait until they experience major life changes that would alter their tax situation to the extent that this adjustment makes sense.

There are several types of life changes that could prompt individuals to file a new IRS Form W-4 to update their withholding allowances, including:

  • Family Changes: Taxpayers can claim different allowances based on their marital status, such as getting married or filing for divorce. Giving birth to another child or adopting a child can also impact allowances. Furthermore, these family changes impact the qualifying allowances for families based on their spouses, children, or dependents. 
  • Employment Changes: If a taxpayer undergoes a change in employment, such as starting or stopping work at a second job, they may benefit from updating their withholding allowances. Taxpayers whose filing status is married filing jointly may also need to update their withholding allowances if their spouse begins or stops working a second job.
  • Tax Deductions or Tax Credits: Employees who experience changes in their expenses may need to adjust their tax allowances if they qualify for itemized deductions or tax credits. These situations include taxes, dependent care expenses, charity contributions, education credits, child tax credits, earned income credits, medical expenses, and interest.
  • Finance Adjustments: Tax withholding allowance changes may be suitable when taxpayers initiate new IRA deductions, alimony expenses, or student loan interest deductions.
  • Taxable Finances: If taxpayers have recently retired, purchased a home, or filed for Chapter 11 bankruptcy, they may benefit from altering their withholding allowances.
  • Non-Taxable Finances: Changes of earnings in non-taxable finances, such as self-employment income, interest income, capital gains, dividends, and certain IRS distributions are not subject to withholdings, but significant changes in how much each of these earnings brings in may require taxpayers to adjust their allowances.

Deciding how many dependents to claim on a W-4 form can significantly impact a taxpayer’s life by determining how much pay they take home throughout the year and how much they owe the IRS in taxes during the tax season.
